Lobelia plant named &#39;KLELE12472&#39;

ABSTRACT

A new and distict lobelia plant named ‘KLELE12472’ particularly distinguished by dark blue flowers and a medium compact, mounding growth habit, is disclosed.

GENUS AND SPECIES

Lobelia erinus

VARIETY DENOMINATION

‘KLELE12472’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of lobelia, botanically known as Lobelia erinus, and hereinafter referred to by the variety name ‘KLELE12472’. The new variety resulted from a controlled cross conducted in June 2006 in Stuttgart, Germany, between female parent lobelia plant named ‘LE 06 0012’ (unpatented) and male parent lobelia plant named ‘LE 06 0028’ (unpatented). A single plant selection was subsequently chosen for further evaluation and asexual propagation.

The new variety was first propagated via vegetative cuttings and in vitro propagation in May 2007 in Stuttgart, Germany, and has been asexually reproduced repeatedly by vegetative cuttings for 15 generations. ‘KLELE 12472’ has been found to retain its distinctive characteristics through successive asexual propagations via vegetative cuttings.

Plant Breeder's Rights for this variety were applied for in Canada on Feb. 17, 2012. ‘KLELE 12472’ has not been made publicly available anywhere in the world more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in a glass greenhouse in Stuttgart, Germany.

1. Dark blue flowers; and

2. Medium compact, mounding growth habit.

DESCRIPTION OF PHOTOGRAPH

This new lobelia plant is illustrated by the accompanying photograph which shows overall plant habit including blooms, buds, and foliage of the plant in full color. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph was taken in spring of 2012 on a 3-month old lobelia plant grown in a 10 centimeter pot in a glass greenhouse in Stuttgart, Germany under normal horticultural practices.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLELE12472’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken in the spring of 2012 on 3-month old plants grown in 10 centimeter pots in a glass greenhouse with a pinch date at week eight. Color readings were taken under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), Fifth Edition (2007).
